debug-rebuild-ref-tree: Copy HEAD into RefTree 

HEAD is not part of getRefs(ALL) and must be copied explicitly.
This allows `jgit debug-rebuild-ref-tree --enable` to convert an
existing repository to use RefTree with a local working tree:

  mkdir testRepo
  cd testRepo

  jgit init
  jgit debug-rebuild-ref-tree --enable

  touch a
  jgit add a
  jgit commit -m initial
